This video made me aware of his channel a few months back and I've been hooked. I really enjoyed the multi-part one where he explained the inner workings of a jukebox[0] [0] ▶ this video

By today's standard Doom doesn't need much processing power. You could probably find exactly the right chip that only has exactly just as many bits of RAM as you need for the lamp's functionality. But that would probably be more expensive to develop and chip than just using standard parts? Even more radical: I suspect with a bit of cleverness you could probably do everything the lamp needs to do with some relays and transistors. But today, that would be more expensive. Compare ▶ this video for the latter approach.
